For CLEP, University of Phoenix (UOP) seems to be the place to go in the Bay Area, but they are scheduling at least several weeks out. Despite what the CLEP list says, none of the UOP sites are closed to non-students, it's just they may restrict the days and times. Also, there is a $25 admin fee per test. Here are my research results for all tests types:

CLEP

UOP Pleasanton
Test days/times: Wednesdays at 9 am and Thursdays at 2 pm.
Lead time: About a month. As of 4/21/08, they were booked to the end of May.

UOP San Jose
Test days/times: Mondays 10:30 and 2 pm
Lead time: At least six weeks. As of the end of April, they were booked until June 23rd

National University San Jose
Did not hear back from the San Jose coordinator (Carlos Escobedo)
If you talk to them, be sure they are the San Jose not San Diego campus

UOP San Francisco
Will start testing in September

Dantes

Foothill College Los Altos
Computer-based Dantes
Test days/times: they will send you info, you schedule online
Admin fee: $25/hour (not sure how this works for Dantes)
Lead time: just a few days
They also do paper-based test proctoring for the same fee

UOP Fairfield
Computer-based Dantes
Test days/times: Varies, Tuesdays/Saturdays or Tuesdays/Fridays, 10 & 1, they will send you a calendar
Lead time: None

UOP Concord
Paper-based Dantes only
Test days/times: Tuesdays and Thursdays at 8am
Lead time: a few weeks


I did not get a hold of Argosy, New College, Oxman, or UOP Livermore. Golden Gate University testing is only for their students.

Oh, and while I'm at it, here's the Pearson location for EC testing:

Pearson Professional Centers
Transpacific Center
1000 Broadway, Suite 470
Oakland, CA 94607
510-836-3171


Please let me know how this works for you or if you have other info!

Edited to remove UOP Fairfield from the CLEP list
